Effect of fertilizers and growth stimulants on the yield and feed qualities of the green mass of the yellow melilot in the Akmola region

Abstract

Abstract This study is aimed at evaluating the effect of various types of fertilizers and growth stimulants on the productivity and quality of yellow melilot. Their increase is necessary to ensure a balanced mineral composition of livestock diet. Research methods include the analysis of field germination of seeds, the study of plant growth at various stages, and the analysis of the agrochemical composition of the soil and feed mass. The field experiments were conducted in the steppe zone of the Akmola region, Kazakhstan with fluctuating air temperature and low rainfall. The results show that the use of fertilizers and growth stimulants significantly increased the field germination of seeds, the content of protein, carotene, and feed units, as well as the yield of the green mass of the yellow melilot. Particularly high rates were achieved with the use of the Fulvimax N and Start Up fertilizers and the Gumato Fosfat N and K growth stimulants. The results indicate the potential of fertilizers and growth stimulants to improve agricultural production and emphasize the importance of choosing the optimal fertilizers to achieve maximum results. The study contributes to the expansion of knowledge about methods of increasing the yield and quality of feed crops, which is an important issue in agriculture.
